PCT No. PCT/JP79/00104 Sec. 371 Date Dec. 13, 1979 Sec. 102(e) Date Dec. 13, 1979 PCT Filed Apr. 23, 1979.This invention is related to a matrix-type fluorescent indicator lamp which is formed of a matrix by making a number of grid thin wires 13 arranged in parallel intersect perpendicular to a number of anode thin wires 11 arranged in parallel within a sealed tube being composed of a glass cover 6 and an insulated substrate 8, and which displays characters and figures as a dotted pattern by making the fluorescent material-applied anode thin wires luminous spot-like where the anode thin wires 11 intersect the grid thin wires 13. In the lamp, said anode thin wires 11 are mutually arranged in parallel not being in contact with the insulated substrate 8 so as to densify luminous spots narrowing the pitch between the anode thin wires 11 arranged in parallel.
